In active transport, materials move from an area of high concentration to an area of lower concentration (goes down the concentration gradient) and it requires or uses energy in the form of ATP (adenosine triphosphate)
The correct answer to this question is a: metamorphosis. Many
insects take on multiple forms through different parts of their lifecycle. For
example, many lepidopteran species (i.e., butterflies) include a caterpillar
juvenile stage. To reach the adult stage, the juvenile stage has to go through
metamorphosis, where its adult form is strikingly different from its juvenile
form.
lolololololololololololololololololololololololololololololololololol!!
Because the molecules that are being transported is moving against its concentration gradient. in other words, its moving from where its low in concentration to where its high in concentration
